It was star-studded night at the 56th annual Grammy Awards. With artists – new and old – coming together, and a handful of Rock and Roll Hall of Fame Inductees taking to the stage. The night included rememberances of Hall of Fame Inductees Lou Reed and Phil Everly, as well as 2014 Rock and Roll Hall of Fame Inductee Dave Grohl taking honors for best rock song for “Cut Me Some Slack,” a collaboration from his Sound City soundtrack that features Paul McCartney, former Nirvana bandmate and fellow 2014 Inductee Krist Novoselic and Pat Smear. From Paul McCartney and Ringo Starr to Madonna to Stevie Wonder, there were numerous Inductees getting into the live act at the Grammy Awards.

Dozens of couples, representing all demographics: gay, straight, interracial, young and old said “I do” during Macklemore & Ryan Lewis’ performance of “Same Love” featuring Mary Lambert and Rock Hall Inductee and seven-time Grammy Award–winner Madonna. Lewis, the group’s producer, told The New York Times, the wedding “will be in our minds the ultimate statement of equality, that all the couples are entitled to the same exact thing.”

Concert pianist, Lang Lang and Metallica also came together performing the heavy metal band's "One." The unlikely pair shocked the masses my making the ostensibly odd pairing work in their favor. According to the Los Angeles Times, this marks Metallica's first performance at the Grammys in more than 20 years. At the 1989 Grammy Awards, Metallica performed the same song, "One," nominated at that time for their album ...And Justice for All.

Last, but certainly not least, Paul McCartney and Ringo Starr reunited on stage performing “Queenie Eye” from Macca’s latest album, New. According to Rolling Stone, this reunion is one of only a handful of times McCartney and Starr have performed together. Starr also performed solo and played “Photograph” from his 1973 album, Ringo.
